Auto-react

Automatically react — and optionally add or remove a role — when a message comes from a chosen user or role.

Dashboard: /guilds/<id>/m/auto-react.

Needs

• No privileged intents — only the message author and their roles are read, never the message content.
• Add Reactions and View Channel in any channel it should react in.
• Manage Roles (with Sylo’s own role above the one being granted/removed) if a rule uses the “also change a role” option.

Settings

• Rules — as many as you like; the first one that matches a message wins. Each rule has:
  • Target users and/or target role — at least one of the two.
  • Channel — optional; leave as “all channels” or lock the rule to one.
  • Emoji — one or more, unicode or a server custom emoji.
  • When to react — every matching message, or a random % chance.
  • Also change a role — optionally give or take away a role on the same trigger (e.g. to track a status like “infected”).
• Per-user cooldown — seconds before the same person can trigger a rule again, regardless of channel.
• Log channel — optional; posts one line per trigger (who, where, and any role change).

Notes

• A rule with neither target users nor a target role, or with no emoji, is dropped automatically — there’s nothing for it to do.
• Reacting and changing a role both happen on the same trigger; if the role change fails (missing permission, role above Sylo’s), the reaction still happens.
